Application filed August 16, 1919. Serial No. 317,877.

To all whom it may concern:

Be it known that I, EDWARD P. SHELDON, a citizen of the United States,residing at New York city, county of lxings, and State of New York, haveinvented certain new and useful Improvements in Collecting and StaplingMechanism, fully described and represented in the followingspecification and the accompanying drawings, forming a part of the same.

- This inventio relates to certain improvements in collec ing andstapling or stitching mechanism, and has been designed particularly foruse with printing machines.

In certain classes of printing machines as heretofore constructed,provision is made for running a web or sheet through without collecting,or cutting and collecting sheets cut from a web and stapling thecollected product, or running through such cut sheets withoutcollecting. Where such collected product was to be stapled, however, aspecial stapling mechanism, usually a cylinder, had to be added to themachine. Vhere sheets were cut from a web and collected this staplingcylinder had to be located below the cutting and collecting cylinders,and this position made it difiicult to get at the stapling cylinder toadjust the wire feed and for other purposes, and where this staplingcylinder was installed in a machine not especially designed for it,certain other mechanisms of the machine had to be moved to accommodatethe cylinder, and the stapling cylinder was difficult to install.

It is the especial object of the present invention to produce an easilyaccessible mechanism in which a collecting and stapling or stitchingmechanism are supported in a common carrier. so that a web or sheet maybe run through the machine without stapling or sheets may be collectedand stapled without any change in the mechanism other than silencing thestapling or the collecting mechanism when desired. It is a furtherobject of the invention to produce such mechanism in which the carrierwhich supports the collecting and stapling mechanism may also carry acutting mechanism by which sheets may be cut from a web and, if desired,collected and stapled, or run through straight or collected withoutstapling.

\Vith these and other objects not specifically referred to, in view, theinvention consists in novel parts and combinations which will bedescribed in connection with the accompanying drawings, in which 2-Figure 1 is a side view partly broken away and partly in section of acarrier for supporting both the collecting and stitching adjusted tocollect and staple a product.

Fig. 7 is a detail view partly broken away and partly in section on line7--7 of Fig. 2, showing the operating mechanism in noncollectingposition.

Fig. 8 is a detail sectional view partly broken away showing theoperation of the stapler in taking a staple length.

Fig. 9 is a plan view of the staple former.

Figs. 10, 11, and 12 are detail sectional views illustrating theoperation of clenching a staple.

Machines constructed in accordance with the invention will include asupport or carrier capacitated to support both a mechanism forcollecting sheets and a mechanism for stapling or stitching thecollected product,

and the support or carrier embodying the invention in its best form willbe capacitated to support cutting devices for cutting the sheets whichare to be collected and stapled from a web, and these mechanisms will beof such character that any or all of them may be silenced or operated asdesired, or removed from the carrier if not wanted, depending on theparticular product which it is desired to produce.

The particular mechanisms employed may be varied within wide limits, butin the best constructions, the collecting, cutting and stapling deviceswill be carried on a rotary carrier, such carrier being employed toeffect high speed production. In the particular constructionillustrated, there is provided a rotary carrier in the form of acylinder 1, mounted on a shaft 2 suitabl supported in bearings 3, on aframe 4 0 any usual or desired construction. This cylinder 1, in

the construction illustrated, is capacitated to support collecting,cutting and stapling mechanisms which may be of any usual 01' desiredcharacter. In the particular construction illustrated, a collectingmechanism is shown supported on the cylinder the sheet taking devices ofwhich are shown as pins 5. These pins are provided in sufficient numberalong the cylinder to effectively take and hold the sheets, and as theyare similar in construction and operation but one will be described.These pins work in guide slots 6, formed in the cylinder wall, the shankof the pin passing through a bar 7, and the pins are normally held inretracted or non-taking position by springs 8 taking against aprojection 9 on the pin and the wall 10 of a recess formed at the innerend of the slot 6. Beyond the bar 7 the pins are formed with a slottedhead 11, in which takes an actuating pin or stud 12 whichis operated tothrow the pin into sheet taking position at the proper time, thisslotted head providing a lost motion for purposes hereinafter referredto. This pin or stud 12 is carried on an arm 13 on a cam shaft 14extending across the cylinder and (see Fig. 2) having a cam roll 15which takes in the groove 16 of an operating cam 17, which is mountedloosely on the carrier shaft 2, this cam being driven throughconnections hereinafter referred to.

Machines constructed in accordance with the invention will becapacitated to support a mechanism for securing together the plies of acollected product where such a product is desired. While this securingmeansmay be of various characters, it w1ll be carried by and operatedfrom the cylinder 1, which carries the collecting pins. In theparticular construction illustrated, these securing devices are astapling mechanism adapted to form and insert wire staples in thecollected product at the points desired, and these staplers may be of an'usual construction, and any desired num er, two such being .illustratedarranged along the cylinder to manner.

staple the product at two points in line with each other. These staplersare of the same construction and are operated in the same As shown eachincludes a staple forming plunger 18 which takes a wire length cut offby a suitable mechanism, not illustrated and which cooperates witha'staple forming horn 19 eccentric to the carrier 'to form the legs ofithe staple in the usual manner. 7 I

In constructions where the staple forming and inserting mechanism iscarried on the collecting cylinder means are provided whereby after thestaple has been formed, it may be withdrawn within the periphery of thecarrier so that the staple will be out of the way of the sheet which isto be collected on the carrier. In the best constructions, furthermore,means will be provided to operate the stapling mechanism so that thestaple is positively inserted in the product as distinguished from theordinary staple insertion effected by rolling contact. In the particularconstruction illustrated, there s provided a hollow head or block 20 setlnto the cylinder wall, this block being provided Withways 21 (seeparticularly Fig. 9) in which is arranged to slide an anvil plate 22which effects the positive insertion of the staple in the product at theproper time. This plate (see Fig. 8) is provided with ears 23 to whichare connected an arm 24 pivoted to an arm 25 loosely mounted on a shaft26 extending across the cylinder frame, the anvll being reciprocated soas to be drawn out of the way of the formed staple as it is drawn intothe carrier by the staple formmg plunger to clear the carrier surface.

-The staple forming plunger is mounted and operated in any usual manner.In the partlcular construction illustrated, it works through guide slots27 formed in the plate 22, before referred to. The inner end of theplunger is recessed (see Fig. 10) to form hooked lugs 28 in which workactuating pins 29 carried on each side of a lever arm 30 clamped to theshaft 26. This shaft 26 is operated to actuate the plunger through a cam(see Fig.2) arm 31 having a cam roll 32 which takes in a groove 33 of acam 34 loosely mounted on the end of the'shaft 2 opposite the pinoperating cam 17, before referred to. The parts are so arranged andproportioned that the plunger is forced outwardly beyond the carrier totake the wire length and after it is taken and the staple formed 1swithdrawn so that the face of the plunger and the ends of the legs ofthe staple carried by it are within the periphery The stapling mechanismmay be silenced when no stapling is desired in any usual way, as forinstance stopping the wire feed;

.or removing the stapling plungers.

In machines embodying the invention in its best form for convenience inconstruction, the cam for operating the'collecting pins will be utilizedfor operating the clenching anvil. While various constructions may beemployed for this purpose, in the particular construction illustrated,the

' shaft 14 has positioned thereon an arm 37 to which is pivoted at 38one end of a cross over link 39, the other end of this link beingpivoted at 40 to the arm 25, before referred to, through which the anvilis operated. In order that the collecting pins and anvil may be operatedindependently of each other, a lost motion is provided both for the pinsand anvil, the slotted head 11 of the pin, before referred to, beingutilized for this purpose, and the guides 21 in which the anvil slidesbeing sufiicientl long 'to permit the anvil to have a su cient idlemovement therein.

Machines constructed in the best form of the invention will includecutting mechanism for severing sheets from a web, and in the bestconstructions this cutting mecha- Y nism will, be also carried on thecarrier 1,

this cutting mechanism including the usual cutter knife 41, mounted inthe carrier with which cooperates the usual spring seated cheeks 42, thec'iitter knife cooperating with a cooperating cutting wood 43 on thecylinder 36, before referred to.

Machines constructed in accordance with the invention will include meanswhereby the stapling mechanism may be operated to insert a staple atevery revolution of the cylinder or carrier, where a collected prodnotis being sent through and no further collecting is to be done, or ifcollecting is to be done, at a number of revolutions, and the collectingpins being likewise operated, to produce different products. while thismay be effected in various ways, the operating cams 17 and 34, beforereferred to, are arranged so that they may be stationary with respect tothe cylinder, which arrangement is used where a product is to be stapledat each revolution, or they may be ,given a movement with the cylinderbut at half the speed thereof, so as to effect the stapling andcollecting function in the particular machine shown at every otherrevolution of the cylinder. .As the same construction is preferablyemployed for each of the cams 17 and 34, but one such construction willbe described. In the particular construction illustrated, referring toFigs. 2 and 7, the cam 17 is secured to a gear 44, which meshes with agear 45 on an eccentric shaft 46. This eccentric shaft carries a gear47, which is adapted to be thrown into mesh with a gear 48 fast on theshaft 2 of the carrier, before referred to. In the construction shown inFig. 2, the parts are shown in the position they occupy when a productis collected, and stapled at every other revolution of the carrier.while in Fig. 46 is shown rocked to throw the gears 45 and 47 out ofmesh with gears 44 and 48, in which position the. stapler is operated tostaple a productat every revolution of the carrier. The pin rods, ofcourse, are likewise in this position operating at every 7 the eccentricshaft revolution of the carrier, and when no collecting is to be donethe pin points are removed so as to keep them out of the'way of thesheet. I

When the parts are irn-the position shown in Fig. 7, owing to the factthat the cams 17 and 34 are loose on the shaft, means are provided forholdin these cams stationary which means may he of any suitablecharacter, as a pair of sliding latches 49, 50, which have slotted ends,and are secured to the bearing blocks 3, before referred to, in anysuitable manner as by bolts 51.

lVith the construction shown and described a very compact arrangement isprovided, all the parts of which are readily accessible and by the useof which extra cylinders and other drivin connections are omitted, and aconstruction has been provided where if desired'a sheet may be cut,sheets collected or stapled, orany of these mechanisms may be silencedas desired.
